Felt by 2 people across nearby locations.
On May 13, 2026 at 22:01 UTC, a magnitude 5.3 shallow crustal earthquake struck 51 km NNE of Namuac, Philippines, at a depth of 35.0 km and coordinates 19.0659°, 121.2754°. This earthquake was detected by 72 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 433, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Philippines, a region characterized by the Manila Trench and Philippine Trench subduction systems, where the Philippine Sea Plate overrides the Eurasian Plate. The nearest mapped fault system is the Philippine Fault. View all earthquakes in Philippines.
